Trying to get going that want to be some sort of minor league for the NFL.
You may think that the age thing means it could work. I think it hurts them .Ore than helps. Maybe if you let more veteran players AND young kids but I'd still bet a huge amount against that league.
No one goes to watch these minor leagues where there's real developed talent. Why would people go watch a bunch of undeveloped kids play? They won't. Not to the level it would take to keep the league alive.
